Dongji Island Introduction
Do you know that there is a marine national park in Penghu? The "Southern Four Islands National Park" of Penghu includes Dongji, Xiji, Dongyuping, and Xiyuping islands, along with surrounding reefs and sea areas. Due to its sparse population, it has maintained its primitive appearance and is an important ecotourism destination. The easternmost island, Dongji, is the largest among the Southern Four Islands and is also the closest island to the main island of Taiwan. It used to serve as a transshipment station for maritime trade between Taiwan and Penghu. The nearby waters have several spiral currents that often lead to shipwrecks, which is why it is called "Black Water Ditch". To protect ships, two lighthouses were built during the Japanese occupation period; the northern Dongji Lighthouse is the highest point on the island, and its black-and-white striped tower is quite prominent. There are also remnants of a Japanese artillery barrack, locally known as "Bingcuo", visible in the northeastern corner, where Japanese troops were once stationed. If you head west from the visitor service center to Bagua Mountain, you can climb up to get a view of Dongji Harbor, Dongji Lighthouse, and the nearby seascape. The layers of Bagua Mountain consist of elongated basalt, and to the left, there is a round rock resembling an eye, known as the "Eye of Dongji." Almost all the coasts around Dongji Island are steep columnar basalt cliffs, and there is a large wave-cut platform in the northeastern corner, locally known as "Daping," where a large number of intertidal organisms can be discovered at low tide. Due to its rich basalt landscape, it, along with Xiji, Toujin, and Tiezhanyu, is collectively designated as the "Penghu Southern Sea Basalt Nature Reserve."
